A heating system for heating liquids, stored in a tank at low ambient temperature, has a heating chamber with an inlet and an outlet for convectively flowing liquid past a flameless heater. Cold liquid is drawn through an inlet line, from the tank near its base and into a heating chamber, absorbs radiant energy from the heater as it travels therethrough. Heated liquid is circulated into the tank through an upper outlet from the heating chamber and back into the tank. Preferably, the heated liquid reenters the tank through a floating discharge flexibly connected to the upper outlet so as to remain dynamically in contact with the liquid at all times, thus avoiding airlocks which would interrupt the convective flow of liquid through the heating system.
